Kana zvasvika kune 3D kudhinda uchishandisa Smooth Overlay Modeling (FDM) tekinoroji, kune maviri makuru mapoka emaprinta: Cartesian neCoreXY, ine yekupedzisira yakanangana neavo vari kutsvaga kukurumidza kudhinda kumhanya nekuda kweinochinjika dhizaini yekugadzira musoro tekinoroji.Huremu hwepasi hweiyo X/Y yepasi bracket assembly inoreva kuti inogona zvakare kufamba nekukurumidza, zvichiita kuti vanofarira CoreXY FDM vaedze kabhoni fiber uye ichangoburwa [PrimeSenator] vhidhiyo apo X-beam inochekwa kubva mualuminium chubhu uye inorema kupfuura kuenzaniswa. .Carbon fiber tubes akareruka.
Nekuti CoreXY FDM maprinta anongofamba munzira yeZ inoenderana nenzvimbo yekudhinda, ma X/Y axes anodzorwa zvakananga nemabhandi nemadhiraivha.Izvi zvinoreva kuti nekukurumidza uye zvakanyanya iwe unogona kufambisa iyo extruder musoro uchitevedza mitsetse madhairekitori, nekukurumidza iwe unogona (mudzidziso) kudhinda.Kudonhedza iyo inorema kabhoni faibha kune aya milled aruminiyamu zvimiro paVoron Dhizaini CoreXY printa kunofanirwa kureva kushomeka inertia, uye ekutanga mademo ari kuratidza mhedzisiro.
Chii chinonakidza nezve iyi "yekukurumidza kudhinda" nharaunda ndeyekuti haisi iyo chete yekumhanyisa kudhinda, asi maCoreXY FDM anodhinda anoapfuura maererano nekurongeka (resolution) uye kugona (senge vhoriyamu yekudhinda).Zvese izvi zvinoita kuti maprinta aya akwanise kufunga nguva inotevera paunotenga FDM style printer.
Linear madhairekitori akagadzirirwa kukotama kune flatness mavakaiswa.Izvi zvinoreva kuti njanji ichapeta chikamu chayakasungirirwa kana chikamu chavanonamatira chisina kuoma zvakakwana.Kana izvo zvakakwana kuti zvindinetse, ini handizive, ini handisati ndashandisa mitsara madhairekitori.
Kune vamwe vakazvipira chaizvo vashandisi veVoron vanongoshandisa njanji dzakatsetseka pasina imwe tsigiro, saka haisiyo yakanyanya kuomarara sisitimu yekumhanya pane imwe yemichina ine mhedzisiro yakanaka.
Iyo CoreXY system inofambisa musoro wayo munzira X uye Y.Iyo Z axis inowanikwa nekufambisa inodhinda deki kana gantry.Zvakanakira ndezvokuti kufamba kunodiwa kwemubhedha kwakaderedzwa, sezvo mafambiro muZ-axis anogara ari madiki uye asingawanzo.
Sezvakataurwa nemumwe mutauri (rudzi rwe), njanji dzemitsetse dzave kutanga kutaridzika zvinorema.Ini ndanga ndichinetseka kuti vaigona kugadzirwa kubva kune chinhu chakareruka senge boron?(chii chinogona kuipa?)
Muchokwadi, ndinofungidzira kuti mhinduro yakanakisa haisi yekuparadzanisa zvinyorwa kubva kune rutsigiro.Printer yangu yakachipa uye inotyisa inoshandisa mbiri yesimbi semagwara uye zvitsigiro, uye ini ndinokahadzika kuti dhizaini iyi inogona kukwikwidza nayo mumhando.(asi kwete chokwadi uye kuomarara)
Kuisa simbi dzakaomeswa simbi pamakona akatarisana anogona kushanda, asi kwete neakagadzirira-akagadzirwa recirculating bhora madhairekitori.
Pakati penzira pane maburi akachekwa nejeti remvura rinoputika kuderedza uremu.Ita rutivi rwekumashure rutivi rwekupinza kuitira kuti kupararira kwechisikigo kwejeti kunogadzira koni shoma uye pasina mitsetse yakapinza kune rumwe rutivi rwemberi kuitira kuti wipers pagedhi (kana akaiswa) arege kuputika kana kucheka.
Dzinongova simbi dzakaomarara.Ingodzigaya kubva mucarbide.Akashandura zvikamu kubva pamapini egeji mune yakaoma 52100 inotakura simbi.
Hazvigoneke sezvo induction kuomeswa kunoshandiswa panguva yekugadzira kunogadzira kushushikana kwemukati muchitima (mamwe maChinese magnesium alloy njanji anogona kunge asina kuomeswa zvachose kuti aitwe muchina).manejimendi……
Muchokwadi, haisati iri tsigiro yakakodzera kune mitsara njanji.Kune simbi dzesimbi dzakaiswa mualuminium tarisa paNadella njanji, iyi ipfungwa asi sezvo aruminiyamu ichida hombe yemuchinjikwa chikamu kuti ive nekuoma kwayo inorema zvakanyanya.
Kambani yeGerman FRANKE inogadzira 4-sided aluminium njanji ine yakasanganiswa simbi mijaho - yakareruka uye yakasimba, semuenzaniso:
Kuoma kwedanda kunowedzera ne square yenzvimbo.Aluminium ndeyechitatu yakareruka uye yechitatu yakasimba.Kuwedzera kuduku muchikamu kunopfuura zvakakwana kubhadhara kurasikirwa musimba rezvinyorwa.Kazhinji hafu yehuremu inokupa danda rakaoma zvishoma.
Uchishandisa grinder yepamusoro, njanji dzinogona kuderedzwa kuita H-chimiro chine dandemutande dandemutande pakati peanosangana ndege dzemabhora (anogona kunge ane 4 point contact, asi iwe unowana pfungwa).TIL: Titanium (alloy) profiles iripo zvakare: https://www.plymouth.com/products/net-and-near-net-shapes/ asi iwe unofanirwa kubvunza mutengo.
Pakazoita dambudziko nePlymouth Tube Company yeAmerica lol.Mushure mekutarisa nevirustotal, miedzo yose haina kuratidza matambudziko, kunze kwe "Yandex Safe Browsing", iyo, mumaonero ake, ine malware.
Ini zvakare ndinofunga kuti njanji dzemitsetse dzinotaridzika zvinorema uye ndinoda iyo pfungwa yeakasanganiswa simbi njanji.Ndinoreva, izvi ndezve 3DP, kwete grinder - unogona kurasikirwa nehuremu hwakawanda.Kana kuti shandisa urethane/mavhiri epurasitiki wokwira wakananga paaluminium?
Ngativimbei kuti hapana anoedza kuivaka kunze kweBePane chirevo chinonakidza muongororo yevhidhiyo nezve kushandiswa kwekabhoni fiber.Zvino fungidzira 5-6 axis muchina unogona kutenderedza 3D yakadhindwa mandrel mune yakagadziridzwa yekutarisa.Hatina kuwana ruzivo rwakawanda nezve CF inotenderedza purojekiti… pamwe ndiyo?https://www.youtube.com/watch?v=VEGMEFynPKs
Hauna kunyatsoidzidza, asi iyo track pachayo haina kusimba zvakakwana here?Iwe unonyatsoda chimwe chinhu chinopfuura kungoita bhuraketi rekona rekubatanidza handrails kune njanji yepadivi?
Pfungwa yangu yekutanga yaive yekucheka huremu nehafu zvakare nekutenderedza makona matatu kubva mumakona panzvimbo yemachubhu, asi uri right...
Iko kuomarara kwakawanda uku kunodiwa mukushandisa uku?Kana zvakadaro, isa bhuraketi "mukati" mukona, zvichida nemakumbo anoshandiswa njanji.
FYI: Ndakaona vhidhiyo iyi ichibatsira kumitemo yechigunwe kune akasiyana maumbirwo ezvimiro: https://youtu.be/cgLnADEfm6E
Ini ndinofunga kana iwe usina muchina wekugaya unogona kupenga nemuchina wekuchera uye kungoboora masaizi akasiyana emakomba uye woswedera pedyo nawo.
Uku, hongu, kushamisika kusinganzwisisike ("asi nei?" Haisati iri mubvunzo unoshanda muHaD), asi inogona kuwedzeredzwa (kufambiswa) neiyo genetic algorithm yekugadzira iyo inonyanya kushanda chikamu.Unogona kuve nemhedzisiro irinani kana ukashandisa yakasimba stock uye woirega ichicheka kamwe muX-axis uye kamwe muY-axis.
Ndinoziva maitiro ebioevolution akatsamwa izvozvi, asi ndinoenda kune mafractals nekuti anotaridzika sesainzi uye haavimbe nekudzokorora kufungidzira.… Zvino ichi chinogona kunge chiri chikoro chekare sezvatinochidaidza kuti, Fractal Punk 90- X?
Ndinofunga kuti mutengo wekushandisa chinhu chakasimba uchapfuura chero mabhenefiti.Iwe wakaisa pasi yakawanda yezvinhu, izvo zvinozoita kuti ive yakakura.
Sei uchifunga shanduko kune yakaoma stocks?Anonakidza optimization matekiniki anogona achiri kushandiswa kune square machubhu.
Zvakare, sekusvika sikweya pombi optimization inoenda, ndinofunga iwe unozonyatso kuwana shanduko shoma mumhando.Iwo matriangles ari mutruss atove akanyanya, iwo mapoinzi ekunamatira anowedzera tekinoroji.Kana iwe ukaturikira izvi kumubvunzo we "chii dhizaini chakanakira iyi application" (senge yakazara zvimiro ongororo ye3D printa kana chimwe chinhu), hongu, unogona kuwana nzvimbo dzekudzikisa uremu.
Imwe nzira inogoneka yekugonesa ndeye topology optimization.Ndakangotamba neizvi muSolidWorks, asi ndinofunga kune mapulagi ekuita izvi neFreeCAD.
Mushure mekuona vhidhiyo, kune zvimwe (zvinei) zvinogoneka nyore mhedzisiro zvinoda kuwedzera optimization (kunyangwe, kunyangwe semuridzi weCore-XY muchina, ini pachangu handione kufarira gomba iri retsuro):
- Yakafambisa njanji padhuze nedivi kuti iome zviri nani (ikozvino ichaona macro-deflection yedanda pamwe nekutsauka kweiyo strut yakaiswa pairi)
-Classical truss optimization: Iyo dhizaini yetruss truss haina kugadziridzwa, uye kunyangwe pasina kuyedza kuita epamberi optimization maturusi, truss dhizaini imunda wakagadziridzwa.Mushure mekuverenga mabhuku ekugadzira mabhiriji, aigona kudzikisa huremu nechimwe chetatu pasina kurasikirwa nekuoma.
Ndichiri mukuita yatove yakareruka (uye inoita seyakaomarara zvakakwana kuti isakanganise kudzokororwa), ini handisi kuona poindi yekuivandudza zvakare, zvirinani kwete pasina kutanga kugadzirisa dambudziko renjanji (sekutaura kunoita vamwe vanhu).
"Averenga mabhuku ekugadzira mabhiriji, anogona kudzikisa huremu nechimwe chetatu pasina kurega kuomarara."
Kucheka *huremu*?Ndinobvuma kuti pamwe akawedzera *simba*, asi huremu hwakawedzerwa hwakabvepi?Yakawanda yesimbi yasara inoshandiswa njanji, kwete trusses.
Shandisa iwo maaruminiyamu screws anoshandiswa neRC vanofarira uye jecha pasi pasi pemitsetse dhairekitori kuti iwe ugone kugera magiramu mashoma.
Ah, uye nenzira, paforamu yemotokari makore gumi apfuura zvakaonekwa kuti kuzadza zvikumbaridzo nefuro kunogona kuwedzera zvakanyanya kuomarara kwedzimwe mota (kuvandudza mabatiro, nezvimwewo)
Saka inogona kunge iri pfungwa yekuyedza kushandisa yakareruka yakatetepa yemadziro chubhu, pamwe yebrazed, brazed, brazed kana yakafanana mounting ndiro yakazadzwa nefuro rinowedzera.
Izvi zvinofanirwa kuve pachena, asi chokwadi iwe unoda kuita chero mhando yekupisa, kunyunguduka, kupisa, kupisa, kupisa mhando pamberi furo risati razadza.
Indasitiri yezvemuchadenga yakafanana neyezinga rehuchi composite mapaneru.Yakanyanya kutetepa kabhoni faibha kana aruminiyamu muviri ine yakajairwa Kevlar huchi chimiro pakati.Yakanyanya kuomarara uye yakanyanya kureruka.
Handifungi kuti mapaipi matete emadziro ndiyo nzira yekuenda nayo.Handina kumbobvira ndave fan hombe yejekiseni-yakaumbwa CFRP (inorasikirwa nezvakawanda zvakanakira UD CFRP, inova kureba kweavhareji urefu hwefilament hunoipa simba rakakura kudaro), uye aluminium haiwanzo kutengeswa yakatetepa kuti ichengetedze. uremu zvakanyanya.Ini ndinofungidzira kuti zvingaite kugaya zvakatsetseka, asi kugogodza kunogona kudzivirira kukuya zvakakwana.
Dai ndaienda nenzira iyoyo, ndaizotora pepa rakatetepa re-bi-directional CFRP kubva kune imwe yandaifarira bhajeti rechigadzirwa saiti, ndoicheka kusvika pakukura, ndoinamira kune yakavharika furo, pamwe ndichiiputira muzvikamu zveCFRP kana fiberglass. .Izvi zvichapa iyo yakanyanya kuomarara mukufamba uye printhead tsigiro shafts, uye iyo wrapper ichapa iyo yakakwana torsional rigidity kuti imirire chero nguva diki inobuda kubva kuprinthead.
Ndinorumbidza kushanda nesimba uye kungwara, asi handigoni kuita asi kunzwa kuti kutambisa simba kuedza kusvina pese pekupedzisira donhwe kubva mudhizaini isina kugadzirirwa remangwana zvachose.Iyo chete inogoneka nzira yekumberi ndeyemisa parallel 3D kudhinda kuderedza nguva dzekudhinda.Kana munhu achinge abira madhizaini ese aya, hapazove nemakwikwi.
Asi ini ndinofunga kubva pachimiro chechimiro ingangove inyaya hombe - simba rekabhoni faibha rinonyanya muaya marefu akavharirwa fiber uye unoacheka ese kuti areruke uye haunyatso shandisa nzira imwechete yekusimbisa inobatsira - ikozvino. kugadzira "pombi" kana CF truss inoruka paunoda, inoshanda munzira kwayo, ingave inoyevedza sezvo vane CNC router kwavanogona kuveza extrusion musoro.
Kuedza kutsvaga kuwirirana pakati pekuita zvaunotaura (iyo ndiyo nzira yakanakisisa) uye kutora nzira iri nyore yeDIY ndeimwe yenharo dzekushandisa izvo dzimwe nguva zvinonzi forged carbon fiber.Asi ini ndinofunga ndakawana zano rekuyedza iwo akafanana ekutanga chimiro, chete muZr magnesium alloy (kana imwewo yakakwira simba magnesium alloy).Yakanaka magnesium alloys ine yakakwira simba kune huremu reshiyo kupfuura aruminiyamu.Ivo havasati "vakasimba" secarbon fiber kana ndikarangarira nemazvo, asi ivo vakaomarara zvakanyanya, izvo zvandinofunga kuti zvichaita mutsauko pane iyi application.
Ini ndinokahadzika kuti "yakareruka kupfuura inofananidzwa nekabhoni fiber tubing" - ndinoreva kuti imhando yekabhoni faibha, yakasimba uye yakareruka kupfuura zvinhu zvakaita sealuminium.
Takashandisa mashoma machubhu eCF mupurojekiti yaive (chaizvo) bepa rakatetepa uye raive rakasimba kupfuura iro gobvu, rinorema aruminiyamu yakaenzana, zvisinei kuti makomba mangani ekumhanya awaida kuwedzera.
Ndinofunga kuti “nokuti ndinokwanisa”, “nokuti zvinotaridzika zvakanaka”, pamwe “nekuti handikwanise kutenga chubhu yeCF” kana kuti “nokuti tiri kuzviita nechubhu yakasiyana/isina kufanira CF Enzanisa netsika.
Tsanangura "Zvakasimba" - sezwi, zvinoenderana nemamiriro ezvinhu, uri kunyatsovavarira kuomarara, kusimba, nezvimwewo?
